A caffeinated variety of the new Cracker Jack’d! brand, “Power Bites,” is one of a number of products cited by the Center for Science in the Public Interestin a letter to the U.S. Food and Drug Administration.

The CSPI alleges the line extension of the classic kids’ caramel and popcorn snack food is one of several foods that seemingly violate federal food regulations and “could lead to serious health problems for children who consume those products.” The letter also cites “Extreme Sport Beans” from the Jelly Belly Candy Co.

A Frito Lay spokesman told Ad Agethat Power Bites will include two flavours “that will contain coffee, a natural source of caffeine, as an ingredient. We stand by the safety of all products in the Cracker Jack’d line, including those that contain coffee. It is worth pointing out the regulation referenced in CSPI’s letter to FDA speaks to caffeine, not coffee.”
